integral from 0 to 1 of sin(pit)

\int_{0}^{1} sin (π t) d t

\frac{2}{π}

Decimal Notation

0.63661 \dots

Solution steps

\int_{0}^{1} sin (π t) d t

Apply u-substitution

: \int_{0}^{π} sin (u) \frac{1}{π} d u

= \int_{0}^{π} sin (u) \frac{1}{π} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{π} \cdot \int_{0}^{π} sin (u) d u

Use the common integral:

\int sin (u) d u = - cos (u)

= \frac{1}{π} [- cos (u)]_{0}^{π}

Compute the boundaries:

2

= \frac{1}{π} \cdot 2

Simplify

= \frac{2}{π}

\frac{d}{d x} (\frac{x}{x ^{2} + y ^{2}})

\int 1 - cos^{2} (x) d x

\frac{d}{d x} (- 4 x^{3} + 4 x)

x^{2}, (0, 3)

\int c (x) d x
